Nanocluster molecular crystals of lacunary polyoxometalates as structure-design-flexible, new inorganic nonlinear materials

摘要

Lacunary polyoxometalates, large inorganic, structure-design-flexible, nanocluster crystals are found to have higher optical nonlinearity than KDP by the powder SHG method. Moreover, the capability of generating ultraviolet radiation down to 300 nm is found.
